A device for reducing and simplification of the installation expenditure, in response to receipt of the security against break-in to house doors and keller

摘要

A device for maintaining the reached security against break-in by retaining all in a house by the strength calculations certain structures and connecting parts, the avoidance of the time - and costly connection to the domestic electrical installation, is characterized as follows:The known roller blind housing, on both sides on its two end faces of the photo - voltaikelemente (1) and (2), which of the dc power supply of the radio motor (5) serve. The desired uninterrupted supply, the effect of the accumulator - arrangements (3) and (4); these are arranged in rows and is centered on a parallel circuit. The radio motor (5) is provided on both sides in the bearings (6) and (7) mounted and serves to drive the polygonal shaft (8), which, in turn, the connection to the roller (9) takes over. The function of the radio motor is supplemented by a detector unit (10), which receives and processes coded radio signals.
