The present invention relates to a means for connecting a front panel of a rectangular parallelepiped built-in unit to a built-in casing portion of the built-in unit, wherein the front panel is assigned to a narrow side of the built-in casing portion.
The built-in unit as described above is a tachograph used in a vehicle. Therefore, the front panel must not only meet aesthetic demands but also be a functional part. In the functional part, for example, a window section for a display, a button box, a guide slit corresponding to a driver and a passenger's data card, and in some cases a take-out slit for a printing slip are formed.
Therefore, the coupling means between the front panel of the tachograph formed in this way and the built-in casing part is a group of components arranged in the built-in casing part, that is, a display, various buttons, a printing mechanism, a data card unit, etc. Therefore, a high-accuracy correspondence must be obtained, and vibrations that inevitably occur during automobile operation and changes in length due to material fatigue due to temperature fluctuations at the assembly location must be avoided. . On the other hand, the tachograph record is a record that can be tampered with, especially with regard to working hours and rest periods, so operations that cannot be confirmed later, for example, from the gap between the front panel and the built-in casing part. Need to be surely avoided.
Ordinarily screw joints protected by a seal are not suitable for this precondition, even though it is not suitable for mass production based on the cost of components and assembly costs. This is because the space required for the installation is insufficient, especially for mounting multiple screw joints on the front surface, and the sealing cap that protects the screw does not provide a reliable sealing function based on experience. is there. In contrast, hooks or pawls that are integrally molded to the front panel require a certain length and space in order to be sufficiently spring-elastic for a locked connection to the assembled casing portion of the front panel. To do. Even if the risk of breaking such a coupling means is neglected, such a fixed form is critical with respect to manufacturing errors, so that the front panel may not be assembled in some cases or in some cases. For the first time, an unstable, no longer play joint is formed based on vibration and extreme temperature fluctuations.
Therefore, the problem that forms the basis of the present invention is a rectangular parallelepiped tachograph front panel that guarantees a certain function in a use environment in a vehicle, particularly a certain function with respect to an unauthorized operation prevention lock, and can be easily manufactured. It is to provide a means that can be assembled to the built-in casing portion of the tachograph by mass production.
In order to solve this problem, in the configuration of the present invention, a frame is formed on the front panel, and the inner width of the frame is larger than the installation dimension of the installation casing portion in a direction transverse to the installation direction. The at least two wall members of the built-in casing part facing each other are integrally molded with tongues or lugs directed outwardly at substantially right angles to the respective wall planes, and the tongues on the frame Alternatively, a groove corresponding to the lug is formed.
Further advantageous configurations of the invention are described in the dependent claims.
By means of the present invention, an advantageous irreversible snap joint is provided that allows quick assembly of the front panel to the built-in casing part and ensures continuous mounting. In this snap connection, the entire front panel is advantageously fitted into the required elastic deformation, in which case the relatively long sliding surface provided causes the frame to expand when the front panel is assembled. enable. Since the removal of the front panel is only possible with special tools without being damaged or destroyed, the connection according to the invention also provides a sealing effect. That is, no additional components are necessary. Therefore, an operation prevention lock is also obtained. This is because the frame covers the coupling means relatively broadly, and the coupling means, i.e. the tongue / lug and the groove arranged corresponding to the tongue / lug, on the inner surface of the frame are externally provided. Because you cannot see. Furthermore, the connection according to the invention is hardly applied in the assembled state, so that shape stability is ensured for a front panel which is advantageously manufactured from plastic.
FIG. 1 is a front view of a tachograph,
FIG. 2 is an enlarged side partial view of the tachograph of FIG.
FIG. 3 is a perspective view of an assembling casing portion of the tachograph according to the present invention,
FIG. 4 is a partial cross-sectional view taken along line A in FIG. 1 with the printer drawer taken out.
In FIG. 1, reference numeral 1 indicates a front panel. This front panel shields the built-in casing portion 2 (see FIGS. 2 and 3) of the tachograph on the front side. Reference numeral 3 indicates a window section. The display on the display 4 can be read from the window section 3. Further, a plurality of buttons 5, 6, 7, 8 are guided on the front panel 1. In this case, the buttons 5 and 8 serve to inform the driver and passengers of getting on, and the buttons 6 and 7 serve to release each data card assigned to the driver and passengers. The cover 9 shields the plug socket holder used for inspection. Guide slits 10, 11, shaped like a funnel inwardly, are assigned to the driver's data card in the assembly casing part 2, preferably on the printed wiring board 12 (FIG. 3). Used to insert into each tachograph read / write unit. The notches 13 and 14 of the protruding projection 15 of the front panel 1 are used for gripping when taking out the data card. The front panel 1 is further provided with a notch 16. This notch is shielded by a drawer front wall 17 assigned to the printing apparatus. In other words, the front wall 17 is inserted into the front surface of the front panel 1 so as to coincide with each other in shape, and particularly in the same plane.
For the sake of completeness, a lock means is assigned to the drawer, and this lock means can be released by operating the button 18 when the recording medium is filled later. Reference numeral 19 denotes a take-out opening for the printed recording medium. Button 20 serves as a printing actuator. A variety of functions and data memories can be selected by the rotary switch 21 also arranged in the drawer. For example, the working time data of the driver and the passenger can be confirmed by cooperation with the buttons 5 and 8. Reference numeral 22 shows a sealing cap assigned to a screw that joins the front panel 1 to the built-in casing part 2. The paired openings 23, 24 and 25, 26 serve to introduce a U-shaped tool when the tachograph is removed from the instrument panel's built-in section or appropriate opening. In this case, the U-shaped legs cooperate with the spring-elastic claws 27 and 28 as shown in FIG. The claws 27 and 28 are formed in a U-shaped component 29, and the component 29 itself is fixed to the side walls 30 and 31 of the built-in casing portion 2 by screws 32 and 33.
The built-in casing part 2, partially shown in FIG. 3, consists of a cover part 34 and a bottom part 35. The cover portion 34 has a cover plate 36, and side walls 30, 31 and a rear wall 37 are integrally formed on the cover plate 36. The bottom portion 35 is formed by a bottom plate 38 and a plurality of legs 39 that are integrally formed with the bottom plate 38 and are arranged so as to overlap the side walls 30 and 31 and the rear wall 37 of the cover portion 34. . One of these legs 39 is indicated by reference numeral 39. The lugs 40 and 41 bent from the side wall to the outside and the locks 42 and 43 formed integrally with the leg portion 39 serve to fit the cover portion 34 and the bottom portion 35 in a bayonet shape. Furthermore, the lugs 40 and 41 form a platform that works for fixing the printed wiring board. A structural part 44 is further assigned to the assembled casing part 2. This structural part 44 serves on the one hand for reinforcement by being coupled to the side wall 31, the rear wall 37, the bottom plate 38, the cover plate 36 and the printed wiring board 12, on the other hand the display 4 or the display. A group, that is, a display, a printed wiring board assigned to the display 4, and a display group holding body including the buttons 5, 6, 7, and 8 are formed. The holding body is assigned to the drawer of the printing apparatus. The guide rail is integrally molded. The second guide rail of the drawer is fixed to the side wall 30. Reference numeral 45 indicates a connector, which symbolically indicates the assignment of the display group to the printed wiring board 12. Reference numeral 46 denotes a support portion that is formed in the structural portion 44 and penetrates the printed wiring board 12 to cooperate with the bottom plate 38.
As is more apparent from FIG. 3, strips 47 and 48 that function as reinforcing members are integrally formed on the end surfaces of the cover plate 36 and the bottom plate 38 facing the front panel 1. Tongue pieces 49, 50, 51, 52, 53 are integrally formed on the strips 47, 48. Advantageously, lugs 54, 55 are located on the side walls 30, 31 of the cover part 34, which are coplanar with the tongues 49, 50, 51, 52, 53 and bent on the end face side. The two angle-shaped portions 56 and 57 molded outward from the side walls 30 and 31 serve as stoppers when the tachograph is assembled. A flag-like member integrally formed on the bottom plate 38 and designated by reference numeral 58 serves for the attachment of the aforementioned screws protected by the sealing cap 22.
As shown in the partial cross-sectional view shown in FIG. 4 and the side view of FIG. 2, the annular frame 59 formed integrally with the front panel 1 covers the assembled casing portion 2 relatively widely, and thus, The area where the coupling means between the front panel 1 and the assembled casing part 2 is present is covered and inaccessible. Grooves 60 formed in the frame 59 are assigned to the tongue pieces 49, 50, 51, 52, 53 and the lugs 54, 55, respectively. The side surface 61 having a locking action of the groove 60 is located in one plane or different planes corresponding to the tongue piece and the lug, and is formed substantially perpendicular to the assembly direction of the front panel 1. Reference numerals 62 indicate sliding surfaces respectively assigned to the grooves 60. Thus, the plurality of ribs 63 that reinforce the front panel 1 are such that the end surfaces 64 of the ribs 63 are located on the front planes of the strips 47 and 48, and in some cases on the front planes of the side surfaces 30 and 31. It is formed to work as a stopper when assembled. Further, the side surface 61 may not be formed at right angles to the assembly direction of the front panel 1. In this case, in one example, the assembly of the front panel 1 is facilitated, and in another example, that is, an example in which the groove 60 is undercut, the assembly is made difficult and the sealing function is enhanced.
It is a front view of a tachograph FIG. 2 is an enlarged side partial view of the tachograph of FIG. 1. It is a perspective view of the assembly casing part of the tachograph by this invention. FIG. 2 is a partial cross-sectional view taken along the line A in FIG.
