Abstract

A limit value detection device for multiple detection of a limit value event has a catch mechanism manufactured using microstructuring technology, having a first and a second catch element, each having a plurality of catches, a pawl configured to engage in a catch intermediate space between two adjacent catches of the first catch element, the first catch element being movable relative to the pawl in a freewheeling direction and movement thereof relative to the pawl in a blocking direction being blockable by the pawl, and an actuating device configured to move the first catch element and the pawl relative to each other in a catch-by-catch manner in the freewheeling direction. The first and second catch elements together form a counting unit in which the counter status for indicating the detected limit value events is determined based on the position of the two catch elements relative to each other.

Dependent claims

A limit value detection device for multiple detection of a limit value event, comprising:

a catch mechanism manufactured using microstructuring technology, comprising a first catch element and at least a second catch element, wherein each catch element comprises a plurality of catches each, wherein the catches of the first catch element engage in the catches of the second catch element, such that the first catch element moves the second catch element continuously and also in a catch-by-catch manner during a catch-by-catch movement,
a pawl configured to engage in a catch intermediate space between two adjacent catches of the first catch element, wherein the first catch element is movable relative to the pawl in a freewheeling direction and movement of the first catch element relative to the pawl in a blocking direction is blockable by means of the pawl, and
an actuating device configured to move the first catch element and the pawl relative to each other in a catch-by-catch manner in the freewheeling direction,
wherein the catch elements of the catch mechanism together form a counting unit in which the counter status for indicating the detected limit value events is determined on the basis of the position or positioning of the catch elements relative to each other,
wherein the individual catch elements of the catch mechanism can each assume a plurality of different unique positions relative to each other, wherein each of these unique positions represents exactly one counter status of the counting unit, and
wherein the counter status is indicated in the sense of a coding, in which the number of possible unique positions of the individual catch elements relative to each other determines the number of available code words.

wherein the catch elements of the catch mechanism together form a counting unit in which the counter status for indicating the detected limit value events is determined on the basis of the position or positioning of the catch elements relative to each other,
wherein the catches of the first catch element and the catches of the second catch element do not engage in one another, and
wherein, in addition to the plurality of catches, the first catch element comprises a drive element configured to engage in the catches of the second catch element in order to move the second catch element on in a catch-by-catch manner.
