DE2009285C3 - Record set for a tachograph - Google Patents

Description

The invention relates to a recording disk set, a tachograph according to the Oberbe-ΓΓ of claim 1.

In a known recording disk set / of the type mentioned (DT-Gbm 17 20 629), the tongues are formed in one piece with the disks or the carrier, so that the disks are connected to one another without any special wedge if they are placed on top of one another in the correct order <>5>. The sector-shaped sections of the disks must be arranged at certain intervals and in a specific direction so that when the recording is finished on each disk, the tongue can be cut off in order to be able to continue recording on the following disk.

In known sets of disks is seen as a disadvantage that the zi of the carrier on the disks transmitting torque and the force with which the tongues are cut off, z. B. by a stationary ordered knife (DT-PS 7 40 846), both act in a direction perpendicular to the axis of the tongues so that it happens kasin that one to transfer the torque sufficiently wide tongue is not cut off during an early separation can be done before cutting if the width of the tongue is sufficient to facilitate cutting It is also considered to be disadvantageous that the relative position of the sector-shaped Aus cuts when assembling the panes is not necessarily determined.

It is therefore the object of the invention to design a set of disks of the type mentioned at the outset in such a way that that, on the one hand, a simpler assembly of the panes in a necessarily correct position is possible is, and on the other hand a reliable torque transmission with the lowest possible resistance to a separation of the tongues is possible. This object is achieved by the characterizing features of the patent claim 1 solved. Advantageous further developments of the invention are the subject of the subclaims.

With the aid of the exemplary embodiments shown in the drawing the invention is to be explained in more detail, for example. It shows

In the F i g. 1 to 4 circular disks la, 16, Ic and It / are shown with the same size and shape, which have sector-shaped cutouts 2a to 2d , each of which tapers from the circumference to the center of the disk. The disks have thin tongues 3a to 3d , each of which protrudes radially from the periphery of the disk near the cutout. The length of the tongues 3a to 3 J is selected taking into account the thickness of the discs to be placed one on top of the other.

they are bent at right angles from the ends of the slots 93, so that the tongue reliably engages the cutout for a positive transfer of the Torque can be brought. The parts 82a, 85. ·; and 86 are like the corresponding parts in FIG. 9 from p educated.

F i g. 11 shows a further exemplary embodiment, the rectangular sections of the panes and the carrier of the exemplary embodiment in FIG. 9 are provided with support disks. For the sake of clarity _{) 0} are only the carrier 104 and the disk 101 "? shown. The support disks 110 and 110a are fastened with adhesive 111 to the rear of the rectangular recess 105 of the carrier 104 and to the rear of the rectangular recess 105a of the disk 101a. Sufficient spaces are therefore provided for the insertion of the folded tongues between the carrier 104 and the support disk 110 and between the disk 101a and the support disk 110a. The parts 102a, 103a and 106 are like the respective parts in FIG. 9 trained.

In the manner described above, the tongues are successively in the rectangular cutouts of the following Seheiben folded over and into the spaces between the cutouts and the support discs inserted, which results in an assembly that ensures reliable support and is still easy to open.

According to a further embodiment, each tongue of a disc in FIG. 11 with slots on be given away on both sides, as shown in FIG. 10 shown is.

The disk set in Fig. 12 has disks 121a to 121a 121c /. which sector-shaped cutouts 122a to 122c / and tabs 123a to 123c /. Furthermore, the disks below have square cutouts 125a to 125c / provided in a number which corresponds to the number of disks to be arranged, which cutouts are arranged at certain intervals along the circumference of the individual Seheiben are. The carrier 124 also has rectangular cutouts 125a to 125c /, the number of which corresponds to the number of corresponding to fastening disks and which are arranged at corresponding intervals along the circumference are. Numeral 126 shows a part which, like the corresponding part in FIGS. 1 and 2 formed is.

The disks 121a to 121a and the tongue 123a of the disk are stacked on top of one another on the carrier 124 121a is folded over into the cutout 125a of the carrier, the tongue 123b of the Seheibe 1216 with both Rectangular cutouts 1256 of the disc 121 and the cutout 1256 of the carrier 124 in engagement stands. Similarly, tongue 123c fits into the rectangular cutouts 125c of the underlying Disks and the carrier. The tongue 123c engages in all of the cutouts 125c / below As can be seen from Fig. 13, which shows how the tongue 123c / engages, the tongue is off across all of them cuts 125 of the discs and the carrier to the rear of the carrier 124 folded so that the discs unc the carrier are reliably connected.

In another embodiment, the tongues 123a to 123c / are de; Carrier 124 glued on by narrow paper strips as in FIG. 5 is shown.

In a further embodiment, the support disk is shown in FIG. 6 or 8 with the back de Rectangular cutouts 125a to 125d of the carrier 124 glued.

Furthermore, the tongue of each disc can be provided with slits on both sides, as in FIG. 10 shown is.

The modified embodiments of disc sets ensure a reliable connection the panes and allow easy and trouble-free lifting of the panes.
