According to the invention, several outward-projecting tongues (49) are formed on the built-in housing part of a parallelepipedal built-in unit and a frame (59), whose inner width is greater than the mounting dimension of the built-in housing, is configured on the front panel (1) that is to be fixed on the built-in housing part. Grooves (60), which are allocated to the tongues (49) and corresponding sliding surfaces (62) are formed on the interior of the frame (59), said grooves and surfaces co-operating with a certain elasticity in the frame to form a one-way snap-on connection.
The invention relates to means for connecting a front panel of a cuboid built-in appliance with its installation housing part, wherein the front panel is associated with a narrow side of the installation housing part.
If the above-mentioned built-in device is a tachograph used in a motor vehicle, its front panel not only has to meet aesthetic requirements, but also represents a functional part in which, for example, a window cutout for a display, keyholes and driver's data cards and passenger assigned guide slots are optionally also formed a dispensing slot for a print document.
The connecting means between the front panel and the installation housing part of such a tachograph must therefore allow a high assignment accuracy to the components arranged in the housing part, ie the display, various keys, a printing unit and the data card and aggregates position changes due to fatigue due to the forcibly given during operation of a motor vehicle vibrations as well as the prevailing at the installation temperature fluctuations. On the other hand, the records of tachographs, in particular the records relating to working and rest periods, are at risk of tampering, so that care must be taken to ensure that an subsequently no longer detectable intervention, for example by a gap between the front panel and the housing part, is reliably prevented.
Conventional secured by seals screw can, apart from the fact that they are not suitable for mass production due to the components and assembly costs, these conditions u.a. also not fair because for the front attachment of several screw the space required for this is missing and experience exerting the screws locking plugs not perform a reliable sealing function. In contrast, need on the front panel molded hooks or claws to be sufficiently resilient for a latching connection of the front panel with the Einbaugehäusetell, a certain length and clearance. Apart from the risk of breakage of such fasteners, this type of attachment is tolerant critical, so that a front panel u. U. is not mountable or, if necessary, only over time due to shocks and extreme temperature changes, a labile no longer backlash-free connection sets.
Out US 4,829,595 A For example, an electronic vehicle device with a housing and a control panel is known. In addition, a first frame member and a second frame member are provided. An upper part of the housing has projections, which projections are aligned parallel to respective housing walls. The projections may engage in recesses and grooves of the first frame members.
The underlying object of the present invention was therefore to provide means that allow a series-fitting mounting of the front panel of a cuboid tachograph with the built-in housing part, which in the Einsatzmilieu in motor vehicle a consistent function, especially with regard to security, ensure and in a simple manner can be produced.
The solution to this problem provides means according to the features of the independent claim 1.
Further advantageous embodiments of the invention describe the dependent claims.
The solution according to the invention offers the advantage of a quick-mounting and a permanent seat of the front panel on the mounting housing part ensuring Einwegschnappverbindung in which preferably the entire front panel is included in the required elastic deformation, the intended relatively long sliding surfaces spreading the frame during assembly of the front panel enable. Disassembly of the front panel is damage or destruction free only by means of a special tool possible, so that the compound of the invention also performs a sealing function, without additional components are required. On the other hand, security of engagement is given because the frame covers the connecting means relatively far and is not recognizable from the outside, where on the inside of the frame the connecting means, i. the tongues / lobes and the grooves associated with the tongues / lobes are located. It should also be noted that the compound of the invention in the assembled state is largely free of force and thus ensures dimensional stability for the front panel preferably made of plastic.
In the following, the invention will be explained in more detail with reference to drawings.

With a cover 9 a diagnosis purposes serving plug socket is closed. Funnel-shaped lowered guide slots 10 and 11 are used to input the data cards of the driver in the respective, located in the installation housing part 2, preferably a guide plate 12 (FIG. FIG. 3 ) associated with read / write units of the tachograph. Recesses 13 and 14 of the bead-shaped projection 15 of the front panel 1 are used for access when removing a data card. In the front panel 1, a recess 16 is further provided, which is covered by a front wall 17 of a drawer associated drawer, in such a way that the front wall 13 in particular flush, in design flush, in the front surface of the front panel 1 inserts.
Merely for the sake of completeness it should be mentioned that the drawer is associated with locking means which, in the event that recording material is to be refilled, can be unlocked by confirming a key 18. 19 denotes an outlet opening for the printed recording material. A button 20 is used to trigger the print. By means of a likewise arranged in the drawer rocker switch 21 can be selected various functions and data storage and, for example, in conjunction with the keys 5 and 8 query the working time data of driver and front passenger. 22 designates a seal cap which connects the front panel 1 to the installation housing part 2. Paired openings 23, 24 and 25,26 are used to insert bow-shaped tools when removing a tachograph from a shelf or a suitable opening in a dashboard. The legs of the temple, as from the FIG. 2 shows, with springy Claws 27 and 28 together, which are formed on U-shaped components 29, which in turn are secured to the side walls 30 and 31 of the mounting housing part 2 by means of screws 32 and 33.
The according to FIG. 3 only partly fitted recessed housing part 2 consists of a cover part 34 and a bottom part 35. The cover part 34 has a cover plate 36, on which the side walls 30, 31 and a rear wall 37 are integrally formed. The bottom part 35 is formed by a bottom plate 38 and formed on the bottom plate 38, the side walls 30, 31 and the rear wall 37 of the cover part 34 overlapping associated legs, one of which is designated 39 formed. From the side walls bent tabs 40 and 41 and integrally formed on the legs latch 42 and 43 serve a bayonet-like assembly of cover part 34 and bottom part 35.
