Claim:
1. A latch device for a flap pivotably mounted on a compartment of an automobile so as to be movable between a closed position and an opened position with a push-push kinematic, the latch device comprising a first actuation part and a second actuation part, wherein the first actuation part is to be fastened on the flap and is moved in an axial direction when the flap is moved between the closed position and the opened position, and wherein the second actuation part is to be fastened on the component, wherein the first actuation part engages with the second actuation part when the flap is moved from its opened position into its closed position, so that after a predetermined first stroke of the first actuation part in the direction of the second actuation part and a subsequent backstroke of the first actuation part, the actuation parts are held on each other in an arresting position, and wherein the arresting position is released by a predetermined second stroke of the first actuation part in the direction of the second actuation part so that the flap can be moved into its opened position, wherein the first actuation part and the second actuation part are disengaged, wherein one of the first or second actuation parts comprises a tappet with a control curve on its outer circumference and the other of the first or second actuation parts comprises a housing and a control ring mounted in the housing so as to be axially fixed and rotatable in the housing, wherein the control ring comprises at least one control projection on its inner circumference, wherein the tappet enters the control ring when the flap is moved from its opened position to its closed position, wherein the at least one control projection of the control ring engages with the control curve of the tappet so that after the predetermined first stroke and the subsequent backstroke, the tappet is held in the arresting position on the control ring, and wherein the tappet is released from the arresting position on the control ring by the predetermined second stroke, so that the flap can be moved into its opened position, wherein the tappet exits the control ring, so that the at least one control projection of the control ring and the control curve of the tappet disengage, and wherein the control curve of the tappet comprises:
