Roller counter

The innovation concerns a roller counter, in particular for electricity meters, with number rollers and Schaltträaern that Are each arranged on a shaft, with one * »of the two Waves in at least one elongated hole of a board is pivoted and with spring force against the other Shaft is pulled.

In a known roller counter one is in an elongated hole guided ratchet shaft with a helical tension spring pulled against a number roller shaft. To set the Counter, the ratchet shaft can be deflected in such a way that number rollers and ratchet wheels are completely outside

Intervention. A manually operated safety lever, which in turn locks into place in the safety division is held, prevents sin deflection of the Ratchet shaft due to impacts, for example when Transportation can occur. The disadvantage of this known roller counter is the great expense. Furthermore, there is the risk that the safety lever will not be pushed back into the safety position after the counter has been reset will.

The innovation is based on the task of creating a simple, iertigüngäkösten saving roller counter which does not require any special handling to secure the deflectable shaft after setting the number rollers to zero are.

The innovation is therefore characterized by at least one bow spring and attached to the ends of the shafts through an elongated hole such that the number rollers and the balance wheels are fully deflected swiveling shaft are still slightly in engagement.

Some exemplary embodiments of the innovation are explained in more detail below with reference to the drawings.

Ee shows: Pig. 1 a roller counter in the front view,

Pig. 2 that in the Pig. 1 roller counter shown in side view,

Pig. 3 another design variant,

Pig. 4 a detail and

Pig. 5 a bow spring.

In Figs. 1 and 2, which will be described simultaneously below, 1 denotes a U-shaped bent plate. In bores 2, 3 of the same a number roller shaft 4 is fixed and in oblong extinguishers 5, 6 a ratchet shaft 7 pivoted. On the number roller shaft 4 there are number rollers 8 and on the switching wheel shaft 7 Ratchet wheels 9 arranged.

On the outside of the legs of the board 1 are punched, substantially U-shaped bow springs 10, 11 arranged, the bores for receiving the ends of the shafts 4 and 7 and thumb grips 12, 13 have.

The ends of the shafts 4 and 7 can be caulked or with Clamping rings 14, 15, which for the sake of clarity are only shown in the pig. 1 are drawn. Furthermore, the shaft ends can be provided with grooves, in which snap the bow springs 10, 11 into place.

The indexing wheel shaft 7 is held in the operating position by the bias of the bow springs 10, 11. * Each of the indexing wheels 9 is in engagement with two number rollers 8. To set the number S> to zero, the shaft 7 can now be pressed down using the thumb grips 12, 13. Because the elongated holes 5, 6 are dimensioned so that the number rollers β and the ratchet wheels 9 are still slightly in engagement when the shaft 7 is fully pivoted, a slight latching can be felt when the number rollers θ are set to zero, which makes it easier to position the numbers.

The bow springs 10, 11 can be dimensioned in such a way that the number rollers S can also be used without actuating the thumb grips 12, 13 can be reset.

Since the number rollers θ and the indexing wheels 9 do not completely disengage even when the indexing wheel shaft 7 is fully articulated, it is generally not necessary to secure the indexing wheel shaft 7 for transport. If such a safety device is nevertheless desired when using very large, heavy ratchet wheels, this can be done in a simple manner with a bracket 16 according to FIG. 1 and 2 indicate identical parts. The bow spring 16 has a flap 17 bent at right angles, which engages in a cutout of the Piatino 1 and only allows the ratchet wheel shaft 7 to be deflected if it has previously been removed from this »

Detail raised from right;:. _ä If a Daureen handle 18 of the bow spring 16 is released again after the zero position, does the externally steered ratchet shaft jump? automatically into the operating position and at the same time the tab 17 into the cutout of the board 1 back.

/ - * In the Pig. 4 and 5, 19 denotes an injection-molded bow spring made of spring-hard plastic, which has blind holes 20, 21 for receiving the ends of shafts 4 and 7. This bow spring is with a molded barb 22 and with a molded tip 23 in corresponding openings attached to the circuit board 1 and, in addition to its spring function, also serves to guide the shafts 4 and 7 longitudinally.

Of course, the Sciialträderwelle 7 on the one leg side of the board 1 can be fixed and pivoted only on the other side.
