DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tachograph, which is provided with a flat rectangular parallelepiped housing and a drawer, and the drawer is fitted into a driving pin driven at the time of a clock. The chart disk is movable between a recording position and an insertion / removal position, said drawer being an additional housing for a data card assigned to the driver, especially for long-term storage of working time data. Related to the type formed for

[0002]

BACKGROUND OF THE INVENTION In a tachograph of the type described at the outset, the opening of the receiving hole corresponding to the data card is advantageously made inaccessible by a drawer which can be locked in a suitable manner. , At least shielded from dust.

A related device is disclosed in DE-A-43 15 833. In this known device, the receiving hole of the data card is formed in a plane, preferably upright, which intersects the mounting plane of the chart disk and is formed directly in the body of the drawer. That is, the device requires a large space requirement in width and height, and is therefore not suitable for installation in a general radio housing. However, for tachographs of the type mentioned at the outset, standardization as described above is advantageous not only for the construction of the dashboard, but also for the selective use of two devices. It is. Furthermore, the upward opening of the receiving hole poses a high risk of dirt and a risk that the guide portion of the drawer is subjected to a very high force when the data card is inserted.

[0004] The German Patent Application Publication No. 43 is mentioned above.
The data card device according to US Pat. No. 15,833, requires unusual operability of the data card,
Apart from the fact that it is not possible to incorporate the device into the roof undercarriage of the vehicle, the arrangement described in this known document does not allow the drawer in any case due to the size and weight of the drawer. This can cause major problems with guide and fixation. This is because such drawers impose high demands, on the one hand, due to the high accuracy of the recording on the chart disk, which is required for accident assessment, and on the other hand, for the built-in environment subjected to vibration. Because.

Another arrangement having the advantage that the receiving holes are arranged independently of the drawer is known from DE-A 44 38 926. In the arrangement disclosed in this known specification, the receiving hole of the data card is such that its opening can be shielded by a relatively high formed front wall of the drawer with the drawer closed. , The stationary housing of the tachograph and the mounting plate fixed in the housing. Although the two receiving holes are provided on one plane parallel to the chart disk by utilizing space, due to the requirement on the front surface which is very cramped in certain types of tachographs, these holes are provided. The two receiving holes must be located relatively close on the chart disk. This makes it difficult to grasp and may come into contact with the chart disk.
Due to such design constraints, it is also not possible to provide a sufficiently large gripping recess at the opening of the receiving hole due to the relatively small height of the front surface of the device. Therefore, in this case,
In order to be able to transport the data card between the gripping position and the read / write position, a carriage operable by a drawer is required. This is
This results in considerable costs and, in addition, when the drawer is opened and the carriage is withdrawn, there is a certain obstruction and an operational danger for the insertion and removal of the chart disk. In addition, in the arrangement known from DE-A 44 38 926, very great care is required when inserting and removing the data card. Furthermore, ergonomic conditions, especially when handling data cards, can be very inconvenient, based on the type of installation of the device in the vehicle.

[0006]

SUMMARY OF THE INVENTION The object of the invention is to improve a tachograph of the type mentioned at the outset, at very low cost and almost independently of the installation position of the device. An object of the present invention is to provide a tachograph that can provide arrangement and operability.

[0007]

In order to solve such a problem, according to the structure of the present invention, the receiving hole arranged corresponding to the data card is provided with the loading of the chart disk on a substantially flat surface in the drawer. Is formed parallel to the installation plane,
The openings of these accommodation holes are provided so that the data card can be inserted into the accommodation holes in a direction transverse to the transport direction of the drawer.

[0008]

According to the invention, in particular, the insertion and removal of the data card can be carried out in all practically effective installation positions of the tachograph in an ergonomically advantageous and special manner. The advantage was obtained. That is, it is not necessary to carefully insert the data card, and rather, the data card can be operated even in a non-lighted cabin, that is, even if it is not clearly visible. Further, the chart disk is located outside the operation area of the data card.

The constructional advantage of the present invention is that it does not require the required space for the receiving hole in the front wall of the tachograph, ie it gives more constructional freedom and allows the fall when opening the device. The risk of fouling of the stowage holes is greatly reduced by dust entering or water entering the dashboard when cleaning it, and the drawer closure also renders the data card stowage inaccessible. The point is that it is shielded. Furthermore, the invention provides a minimum structural height for the drawer or front shield.

In FIG. 1, a tachograph rectangular parallelepiped housing selected as an embodiment is denoted by a reference numeral 1, and a front wall 2 of the housing 1 is provided with a display 4 assigned to the front wall 2. Window opening 3 is formed. Reference numeral 5 indicates a shielding member on the front surface of the drawer 6 guided in the housing 1. Of the keys 7, 8, 9, 10, 11, and 12 supported on the front wall 2, the keys 7, 8 and the key 9 marked as a menu key are used to call at least the most important working time data. Assigned to the first driver or the second driver. Key 1
0 and 11 are used for advancing and rewinding each of the called data records, and a key 12 is provided for unlocking and releasing the drawer 6. By means of the seal marked 13 the diagnostic bush (Diagnosebuchs
Access to e) is protected.

According to the plan view of the drawer 6, partially drawn out of the housing 1, shown in FIG. 2, the tachograph contains two chart disks 14, 15 arranged at a predetermined distance from each other. It is understood that it is formed for. For convenience, the network display for explaining the record, which is usually printed on the chart disks 14 and 15, and the numbers assigned to the time scales 16 and 17 are omitted. Both chart discs 1
4 and 15 are fitted into a non-circular entraining pin 18 which is integrally formed with a mounting portion (not shown). The mounting portion is driven by a traveling mechanism provided in the drawer 6 in accordance with the time of a clock. Reference numeral 19 designates a plate, which is pivotally mounted on the drawer 6 and serves as a recording support base for the chart disk 14 located above. At this time, the plate 19 is supported on the side surfaces 20 and 21 of the drawer 6 by the integrally formed grip plates 22 and 23. An opening in plate 19, indicated by reference numeral 24, is necessary to pivot plate 19 over entrainment pin 18.

A guide rail (not shown) corresponding to the drawer 6 is fixed to a side wall (not shown) of the housing 1 in detail, and these guide rails are formed on side surfaces 20 and 21 of the drawer 6. Groove 25,2
6 is engaged.

As can be seen in particular from FIGS. 3 and 4, free recesses are formed on the underside of the bottom 27 of the drawer 6, which are advantageously mounted flush with the bottom. Drawer 6 with cover plate 28
The receiving holes 29 and 30 are formed to extend in the transverse direction to the transport direction. A web 31 separating the two receiving holes 29, 30 serves as a stopper for the data cards 32, 33. Reference numeral 34 denotes a contact area of the data card 33, and an indicating arrow 35 indicates an insertion direction of the data card 33. In FIG. 2, the data card 33 is located at a position after being removed from the drawer 6, or It is shown in a position before insertion into the drawer 6.

According to a particularly salient feature of the invention, relatively large gripping recesses 36, 37 are provided. The holding recesses 36 and 37 allow the plate 19 to be easily held, and the data cards 32 and 33 to be easily held, especially at the time of removal. Guide surfaces 38, 39, 40, 41, 4 acting in two directions are provided on both sides of these holding concave portions 36, 37 or the receiving holes 29, 30.
2,43,44,45 are assigned. Further, a positioning surface is integrally formed on the front wall 2 of the housing 1,
One of these positioning surfaces is shown in FIG. Positioning surface is drawer 6
When closing the data card, it is useful to indirectly insert the data cards 32, 33 that have not been completely inserted into the accommodation holes 29, 30.

As can be seen from FIGS. 2 and 4, frames 47, 48 are formed inside the free recesses, and these frames 47, 48 are assigned to the receiving holes 29, 30 or the data cards 32, 33. Contact supports 49,5

It is advantageous if they are integrally formed as one component. At the contacts, i.e. at the contacts of the two contact supports 49, 50 (one contact is designated by the reference numeral 51), a flexible strip conductor 52 is advantageously assigned, which strip conductor 52 comprises: It is laid in a passage 53 formed in the drawer 6 and is suitably guided on a printed circuit board fixed in the housing 1 which supports the electronic components of the tachograph. In FIG. 2, the strip conductor 52 located on the contact 51 is broken in the area of the contact 51 for the sake of clarity.

Furthermore, the drawer 6 may be equipped with a device, for example a suitable lever transmission (Hebelgetriebe).
This lever transmission cannot slide the data cards 32, 33 to their end positions by the respective positioning surfaces 46 when the data cards 32, 33 are not correctly inserted or when the drawer 6 is closed. Indeed, in the case where the drawer 6 protrudes from the accommodation holes 29 and 30, the drawer 6 is prevented from closing in cooperation with the tachograph housing 1. It is also conceivable that the receiving holes 29, 30 and the contacts 51 can be incorporated into the drawer 6 as a functionally completed component group. Although not common,
Inserting the data cards 32 and 33 in the transverse direction with respect to the longitudinal direction of the card can also be performed if appropriate printing on the data cards 32 and 33 and appropriate arrangement of the receiving holes 29 and 30 are performed. A solution change embodiment.
