DOOR HANDLE ASSEMBLY Russian patent published in 2017 - IPC E05B9/00 E05B1/00 H01L41/08 H05B43/00 

FIELD: construction.

SUBSTANCE: door handle assembly comprises the inner handle with a flange connected by a hollow stem to the outer handle, the latch located on the inner handle and connected by a drive rod passing inside the hollow stem with the pawl and the first limit switch, and the first light source arranged on the outer handle. Wherein the door handle assembly comprises the light sensor arranged on the outer handle, the second light source arranged on the inner handle, and the means for converting kinetic energy of turning the outer and the inner handles into light energy, comprising the cylindrical housing with the gear ring and the projection on the inner lateral surface, mounted rotatably inside the inner handle flange and having the first cover with an opening for connection to the hollow stem and the second cover with an opening for the free placement of the hollow stem mounted with the possibility for movable connection relative to the side surface of the cylindrical housing. A spring motor is mounted inside the cylindrical body on the second cover, having the input gear mounted on an axis fixed to the second cover and engaged with the gear ring of the cylindrical housing and the output gear. Inside the cylindrical body there are also the second limit switch, which engages with the projection of the cylindrical housing while rotating, the piezoelectric generator with a piezoelectric plate cooperating with the output spring motor gear when rotating the cylindrical housing, and sequentially connected to the piezoelectric generator the voltage converter and the controller, to the data inputs of which the light sensor, the first and the second limit switches are connected and the outputs are connected to the first and the second light sources.

EFFECT: increasing the operational reliability.
