Device for adjusting a dosage with a limiting mechanism for a device for administering a product
First Claim
1. A dosing device for a device for liquid product administration with a dose limiting mechanism, comprising:
- a first rotating limiter with a first stop formed in circumferential toothing on a surface of the first rotating limiter,a second rotating limiter with a second stop formed in circumferential toothing on a surface of the second rotating limiter,wherein the toothing of the second rotating limiter engages and follows movement of the toothing of the first rotating limiter during dosing movements with a transmission ratio defined,wherein the second rotating limiter does not move relative to the first rotating limiter during liquid product administration, andwherein the first stop and the second stop each perform rotating movements in such a manner that at least one of the first and second rotating limiters performs multiple rotations in engagement until the first and second stops come into blocking contact with one another in a stop position, whereby a blocking of the movement of the first and second rotating limiters relative to each other is effected and further rotating of the first and second rotating limiters in a dose-increasing direction is prevented.

Abstract
Dosing device for an administration device with a limiting mechanism, comprising a first limiting means (50) with a first stop means (52), a second limiting means (30) with a second stop means (32), wherein the second limiting means follows movements of the first limiting means during dosing movements with a defined transmission ratio, and wherein the first and the second stop means each describe a path curve by their movements in such a manner that the two path curves intersect in at least one point or come so close together that the stop means contact one another in a stop position, whereby a blocking of the movement of the limiting means relative to each other during dosing movements can be effected in that the respective path curves described by the first and second stop means are closed and can be run through preferably multiple times by the first stop means, by the second stop means or by both stop means until the stop means contact one another at the stop position.
