Definitions

  • the invention relates to a housing for a tachograph with a first housing component which receives the measuring and recording elements of the tachograph and a second housing component which is pivotally connected to the first housing component and serves as a cover and which serves to accommodate drive means assigned to the recording media used and on its front side has a window which enables the observation of various display means arranged in the cover.
  • the structural concept of the current tachograph is known to be determined by the diameter of the chart disks used as recording media and by their registration position in the tachograph, namely in a plane perpendicular to the axis of the device, the diameter of the chart disks due to the large number of data to be recorded and a sufficient resolution of the Recordings are not arbitrarily selectable.
  • various function groups are arranged in the cover, but at least display means for the speed and a drive serving to drive the diagram disks, as well as suitable centering and driving means for the diagram disks, that the housing facing the diagram disks serves as a guide and registration document
  • the back of the lid is relatively deeply immersed in the housing when the lid is closed and that the lid can be swung open in such a way that the inserted chart disc faces the viewer in as many installation situations as possible for the tachograph when the lid is open.
  • Such a holder which means additional manufacturing and assembly costs and when using a considerably larger dashboard cutout and a greatly restricted opening angle, is shown in DE-A-27 34 067, for example.
  • EP-A-16994 shows a less complex solution for the recessed installation of a conventional tachograph in a dashboard.
  • the tachograph is assigned an aperture with which the swiveling gap in the dashboard, which is required because of the swing-open cover, can be covered when the tachograph is closed, i.e. H.
  • This solution also requires a relatively large dashboard cutout for the installation of the tachograph.
  • the aim of the present invention was therefore to find a housing architecture that optimally meets the various requirements that have recently been placed on the installation of tachographs, in particular the space required for the opening of the cover is reduced, but the display area is as large as possible, d. H. is largely designed to fill the cross-sectional area of the housing, and which offers sufficient installation flexibility with regard to more designer freedom in the design of a dashboard.
  • the solution to this problem provides that the first housing component is connected to the second housing component in two separate bearings in such a way that when the second housing component is opened, part of the same is immersed in the first housing component and that at least one part of the immersing part of the first housing component Approach assigned to the second housing component with a front lying substantially in the plane of the front surface of the second housing component and at least one lid-independent edge formed by the intersection of this surface with the adjacent housing wall and that the window cutout of the second housing component, based on the cross-sectional area of the Housing, is designed to fill the format so that the pivot axis of the two housing components crosses the window opening.
  • a preferred embodiment is characterized in that the first housing component is cuboid and that the end faces of the two housing components which are located transversely to the pivot axis are each essentially in one plane, so that in the respective side walls of the first housing component pivoting of the second housing component enables cutouts and that both the recesses and the bearing points can be veneered on the end face at least in the closed state of the second housing component by means of wall elements integrally formed on the second housing component with its end faces.
  • the object of the invention satisfactorily solves the problem in all areas, it can be used both in cuboid and cylindrical housings and allows both aesthetically advantageous and spatially relatively compact tachograph designs. It also allows a consistent sealing effect between the cover and the housing and avoids installation difficulties due to possible tolerance-related differences in parallelism between the pivot axis of the cover and the dashboard contours lying in parallel, in that at least one edge of the housing, i.e. a fixed edge of the tachograph, lies in its front surface and thus alignment of the tachograph in relation to the dashboard, in particular if, according to the exemplary embodiment, the tachograph is designed without an overlapping edge, can be carried out with minimal adjustment effort. It is also important that the solution found avoids, above all, the aesthetically disadvantageous swivel gap problem between the movable cover and the adjacent dashboard contours or fixed housing contours.
  • a tachograph 2 is arranged such that its front surfaces 3 and 4 and, for example, an adjacent portion 5 of the dashboard 1 are substantially in one plane.
  • the instrument front surfaces 6 and 7 adjacent to the tachograph 2 are also formed with the same surface area as the front surfaces 3 and 4 and the dashboard surface 5, so that there is a flat overall picture with regard to the vehicle instrumentation.
  • the front surfaces 3 and 4 of the tachograph 2 are formed on the one hand on the pivotable cover 8, on the other hand on a housing attachment 9 to be described in more detail below, and that at least speed display means 11, 12 are provided by a circular window 10 formed in the cover 8 Route counter 13 and display means for the time 14, 15 and 16 are visible.
  • the cover 8 on which a rectangular or square window cutout can of course also be formed, can be locked in a known manner by means of a lock 17 with the cuboid housing 18 (FIG. 2) in the selected example, while the adjusting buttons 19 and 20, as usual, preselect the Serve time registration.
  • the front-side parting line between cover 8 and housing 18 is designated by 21.
  • Fig. 2 Both the side view (Fig. 2), in which the desired flush installation of the tachograph 2 in the dashboard 1 is indicated, as well as the top view (Fig. 3) show - for the sake of simplicity, elements of a tachograph that are not essential to the invention have been omitted - that the lid 8, which in known manner can be formed as a one-piece, pot-shaped housing or, as shown, consists essentially of a frame 22 and a hood 23 connected to it - in addition, a sealing ring 50 and a windshield 51 is shown in Fig.
  • the cover 8 is held closed at two points, preferably in the region of the two corners which pivot outwards.
  • the lock 17 or its lock body and the bolt 28 fastened thereon are assigned a further bolt 30 coupled via a push rod 29 mounted in a suitable manner in the cover 8.
  • the key 27 serves in a known manner as a handle for pivoting the cover 8, while an opening 31 formed in the cover 8 is provided for carrying out centering and driving means, not shown and assigned to the diagram disks.
  • a sealing cord 33 inserted into a suitable groove in the cover 8 is assigned to the closing plane between the outwardly pivoting part of the cover 8 and the housing 18 or the contact surface 32 on the housing 18, and that preferably, deviating from the one shown in FIG 2 shown representation, the pivot axis of the cover 8 lies in the closing plane and may not be formed parallel to the front surface 3.
  • the transitions between the wall elements 39 and 40 and the side walls of the housing 18 can be designed as labyrinth seals in the form of a web engaging in an annular groove.
  • axles 44 are fastened in bearing eyes formed on wall reinforcements 42 and that the frame 22 of the cover 8 has bearing holes 45 associated with the axes 44 and recesses 49 associated with the bearing eyes 43.
  • the wall reinforcements 42 serve the cover 8 as stops, in that, with the inwardly pivoting part of the cover 8, which, when the cover 8 is closed, with the interposition of a sealing cord 46 embedded in the cover 8 on the inside of the housing attachment 9 according to FIG. 4 is present, interact.
  • the housing attachment 9 which, if this is necessary due to design reasons, for example if the housing 18 is to be designed with an intermediate wall, can also be formed as an additional part and can be firmly connected to the housing 18, one by the intersection of the front surface 4 with the adjoining housing wall 48 has an edge 47 which, as it were, as a stop edge permits problem-free alignment of the tachograph 2 when it is installed in the dashboard of a vehicle.
  • the parting line between the cover 8 and the housing extension 9 could also be designed in a straight line, whereby if the square housing cross section is to be maintained, a relatively narrow housing extension 9 would have to be formed and the working time adjustment buttons 19, 20 on the cover would be assigned.
  • the front surface of the housing attachment will present itself as a relatively narrow ring section, so that the working time setting buttons should preferably be designed as key buttons or sliding elements.
