lock drive

Abstract

A locking drive device for locking and unlocking a leaf of a window or a leaf of a door comprising: a housing; a mechanical locking accumulator for locking said leaf via energy storable in the locking accumulator ; a mechanical unlocking accumulator for unlocking the leaf via energy that can be stored in the unlocking accumulator; a tensioning force for pretensioning the energy accumulators that can be loaded by the closing leaf means, the tensioning means can be coupled with each accumulator; and the control means. In this case, the discharge of the pretensioned locking energy store can be triggered via the control device to lock the leaf, and the discharge of the prestressed unlocking energy store to unlock the leaf can be triggered, and the tensioning The device is connected to the energy accumulators via a coupling which, when the leaf is open, can be run in idling in order to cancel the coupling between the tensioning device and the energy accumulators, and which can be operated in When the leaf is closed, the tensioning device and the energy accumulators are coupled to each other, so that the energy accumulators are prestressed by the closing leaf.

Description

technical field [0001] The invention relates to a locking drive device for locking and unlocking a leaf of a window, of a door or the like. Background technique [0002] Via such a locking drive device, the relevant window or door leaf can be automatically locked and unlocked via its associated locking fitting, whereby corresponding manipulation of the locking fitting is correspondingly simplified. [0003] However, hitherto common locking drives of the type mentioned at the outset have the disadvantage that after the locking or unlocking process should be carried out relatively quickly, the movement speed of the drive required for this must be relatively high, but this is now Corresponding noises are then produced, which become more disturbing the faster the drive is moved. Contents of the invention [0004] The object underlying the present invention is to provide a locking drive device of the type mentioned at the outset, with which a direct automatic locking and unloc...
