Abstract

The description relates to an electronic lock system (10) comprising a recessed grip (14) which can be mounted on a door leaf (12) or the like, in which a lockable grip lever (16) is held by one end (18) around an axis (20) parallel to the door leaf (12) by the recessed grip (14) or by a drive shaft (22) for a bar lock, sash lock or the like (24) which is held therein, and further comprises a locking device (26) by which the grip lever (16) can be locked into its position in which its is swiveled into the recessed grip (14). According to the invention, the locking device (26) is constructed in a modular manner and comprises the following exchangeable components (modules): a base module with a movable bolt which, in its locking position, secures the grip lever in its swiveled in position, and with a device for supplying electric energy (e.g., a battery) for driving the movable bolt, which base module can be inserted through an opening formed by the recessed grip and can be secured therein. Also provided is an application module having the shape of a panel which covers the end of the base module inserted through the opening and whose panel surface projects into or through an aperture in the free end of the hand lever (16), or in which the hand lever is shortened in such a way that it releases the panel surface.

Claims

1. Electronic lock system (10) comprising a recessed grip (14) which can be mounted on a door leaf (12) or the like, in which a lockable grip lever (16) is held by one end (18) around an axis (20) parallel to the door leaf (12) by the recessed grip (14) or by a drive shaft (22) for a bar lock, sash lock or the like (24) which is held therein, and further comprises a locking device (26) by which the grip lever (16) can be locked into its position in which its is swiveled into the recessed grip (14), characterized in that the locking device (26) is constructed in a modular manner and comprises the following exchangeable components (modules):

a) a base module (32) with a movable bolt (28) which, in its locking position, secures the grip lever (16) in its swiveled in or folded in position, and with a device for supplying electric energy (e.g., battery or storage cell) for driving the movable bolt, which base module (32) can be inserted through an opening formed by the recessed grip (14) and can be secured therein;

b) an application module (56) having the shape of a panel which covers the end of the base module inserted through the opening and whose panel surface projects into or through an aperture in the free end of the hand lever (16) (FIGS. 1A to 1D) or in which the hand lever is shortened in such a way (FIGS. 9 and

     10) that it releases the panel surface.
